The S&P 500 bounced back 2% last week after scraping against 6-month lows. Mixed headlines on the Iran conflict explained much of this tug-of-war, yet markets are still holding their breath. For many traders, the rally felt counterintuitive: How can equities rally so furiously if geopolitical uncertainties remain unresolved? When looking at Tuesday’s major bounce in […]
negative gamma
The New Volatility Regime
Over the past several weeks, we have consistently highlighted the market’s growing fragility. From the negative gamma “trapdoor” to the destabilizing impact of geopolitical shocks, the message has been clear: this is no longer a range-bound market. Last week confirmed those warnings, as the S&P 500 is down nearly 9% from all-time highs. On Thursday and Friday, traders […]
After OPEX: Market Loses Its Shock Absorber
The options market has just cleared one of the largest structural events of the quarter, as Friday’s OPEX saw nearly $1.4 trillion in delta notional expire for the S&P 500. Because significant positions have now rolled off from the March expiration, the market has lost an important stabilizing force just as macro pressures begin to build. […]
March OPEX: Tipping Point or Turning Point?
Fragility, Risk, and Potential Vol Reset As the S&P 500 enters OPEX week, we echo the same theme of the past few weeks: this market remains fragile. Last week’s selloff pushed the index below the three-month trading range of SPX 6,800-7,000 that had held since late 2025, subsequently closing down 5% since mid-January. The conflict with Iran continues […]
Geopolitical Risk Hits a Fragile Market
Markets entered last week on fragile footing. In our previous Sunday note, we emphasized how negative dealer gamma, extreme put skew, and heavy 0DTE options activity set the market up for a trapdoor scenario. This created a market structure vulnerable to sharp drops and spikes in volatility, as we saw play out last week. The dramatic […]
The Options Market Trapdoor
Over the past week, the topic of volatility has returned to the forefront. While the market has been largely range-bound, underlying support remains tenuous. Simultaneously, traders have begun more actively paying for downside protection. Given the backdrop of flaring geopolitical conflict, we see assymetric downside risk forming as trader uncertainty and negative gamma threaten to unlock the […]
Right Tail Risk Is Building in the S&P 500
The market spent most of last week locked in the SPX 6,800–6,900 range that has largely held since Thanksgiving. Wednesday’s VIX expiration and Friday’s monthly OPEX defined the week’s rhythm, while negative gamma positioning and elevated single-stock put demand maintained pressure under the surface. Our historical OPEX data suggests the market is positioned for a […]
Record 0DTE volume reshapes the S&P 500
Record 0DTE Volume in 2025 Has Changed the Game We wrapped up 2025 with the S&P 500 up 18% for the year—a solid result in the face of tariff headlines, global conflicts, and inflation concerns. One of the major options market stories of the past year has been the growing role of 0DTE options: same-day expiration […]
Subdued Volatility and the Setup Into Year-End
Subdued Vol Meets Negative Gamma Weakness in AI-related stocks dominated market headlines last week, most notably for Oracle and Broadcom. This pushed the market downward, before the rebound on Thursday and Friday. Despite the market trending down for three consecutive days, implied volatility remained surprisingly subdued: put skew remained average, and ATM implied volatility sat […]
FOMC Reset: Vol Crushes, Stocks Lift Higher
Last week began with quiet anticipation of Wednesday’s FOMC. When the Fed announced the 25 basis point rate cut and Treasury bill purchases, the reaction was immediate. Equities surged, with the SPX breaking out above our 6,845 Volatility Trigger to approach all-time-highs near the 6,900 resistance level. The options market had priced in meaningful event-related volatility surrounding FOMC, and […]
